Method for the grinding of a gear wheel workpiece using a dressable worm grinding wheel, wherein the worm grinding wheel is rotationally driven about a tool axis of rotation and the gear wheel workpiece is rotationally driven about a workpiece axis of rotation, and relative movements are executed between the worm grinding wheel and gear wheel workpiece, and wherein after the execution of a dressing procedure of the worm grinding wheel, which is carried out by means of a rotationally-drivable dressing unit, the following steps are carried out: executing a relative shift movement between the worm grinding wheel and gear wheel workpiece parallel to the tool axis of rotation, executing an axially-parallel relative movement between the worm grinding wheel and gear wheel workpiece in parallel or diagonally to the workpiece axis of rotation, wherein a ratio between the shift movement and axially-parallel relative movement is specified, which is variable.

The present disclosure discloses a method for chip-removing gear manufacturing machining of a workpiece by means of a tool, where a rotation of the tool takes place in generating coupling with a rotation of the workpiece, in particular gear manufacturing machining of a workpiece by skiving, wherein the gear manufacturing machining is carried out in a plurality of machining steps, wherein the center distance and/or a rotational angle between the workpiece and the tool superimposed on the generating coupling is/are changed between two machining steps, so that the tool will cut in the machining steps a respective contour that extends alternately closer to a first and a second flank of the target toothing of the workpiece. According to the present disclosure, the same rotational angle may be used for a plurality of machining steps taking place closer to a second flank.

A block assembly for locking a toothed gear housed in a frame includes a body shaped to couple to a portion of the frame adjacent to the gear for translation in a first direction parallel to an axis of the gear, and a locking block coupled to the body that includes at least one locking tooth shaped complementary to at least one gear tooth of the gear. The block assembly further includes an adjustment mechanism operable, when the body is coupled to the frame, to move the locking block in a second direction that is substantially orthogonal the axis of the gear, such that at least one locking tooth is received between a circumferentially spaced pair of the gear teeth to prevent movement of the toothed gear.

Tool electrodes for and methods of electrical discharge machining are provided. In one exemplary aspect, a tool electrode for machining features into a workpiece is provided that allows for increased machining speed without sacrificing the quality of the machined features. Moreover, a tool electrode is provided that eliminates or reduces the high cost associated with customized tool electrodes. In particular, a tool electrode is provided that includes a plurality of electrode elements arranged and spaced apart in a digitized matrix representative of a tooling shape for machining features into a workpiece. The plurality of electrode elements are spaced apart from one another and arranged in the digitized matrix by digitizing an analog electrode tool configured to machine the feature into the workpiece or a volume of the feature to be machined into the workpiece.
